Definitions
- the present invention relates to a cassette transferring machine, and more particularly to a cassette transferring machine which supplies a plurality of cassettes such as tape cassettes consecutively one by one to a tape treating machine.
- a tape treating machine In manufacturing magnetic recording tape cassettes there are used various tape treating machines.
- a tape treating machine is a magnetic recording tape loading machine wherein a magnetic recording tape is loaded into a tape cassette chamber with both end portions of a roll of a magnetic recording tape fitted with the corresponding leader tapes fixed to the respective hubs already mounted in a tape chamber of the tape cassette.
- Other examples of tape treating machines are such as a music tape recording machine and a performance test machine.
- a tape cassette feeding machine for use in a tape treating machine is described in U.S. Pat. No. 406,286.
- the tape cassette feeding machine described therein is shown in FIGS. 18 and 19, of the instant application wherein a plurality of tape cassettes 2 to be treated are laid in a lateral attitude and stacked one above the other as shown in FIGS. 18 and 19 in a vertical magazine 120.
- the vertical magazine 120 is so bent as to provide an arcuate path at the bottom portion thereof whereby the respective tape cassettes 2 move downwardly changing the vertical attitude when passing through the arcuate path.
- the lowest cassette is taken out from the opening 121 defined in the bottom end of the magazine 120, one at a time.
- the tape cassette feeding machine disclosed in the prior art has, however, such drawbacks that each of the cassettes must be placed manually into the path of the magazine 120 from the top opening adjusting the attitude of the cassette, making the system inefficient, preventing from automatic treating of the tape cassettes.
- a further drawback inherent in the prior art cassette feeding machine is that each of the tape cassettes has to be supplied to the path of the magazine 120 oriented in the same direction, otherwise the magnetic recording tape could not be properly loaded in a cassette chamber. With the top face and the bottom face of the cassette reversed, the magnetic recording tape would be taken up by an undesired hub.
- the respective tape cassettes already treated are discharged downwardly with a random attitude, so that they must be collected again reorienting the attitude or must be put in a delivery box for transferring the cassettes to the subsequent process. These steps are also troublesome.
- an essential object of the present invention is to provide a tape cassette feeding apparatus which supplies every cassette at a predetermined attitude to a subsequent treating apparatus.
- Another object of the present invention is to provide a tape cassette feeding apparatus which provides for the collection of a plurality of tape cassettes in a container with the attitude thereof aligned in one direction so as to facilitate treating of every tape cassette in the subsequent stage.

- FIG. 1 of the drawings there is shown a magazine container 1 utilized in the apparatus according to the present invention, which is in the form of a transversely longitudinal rectangular box having an upper opening and a pair of side walls 1a and 1b. Inside the side walls 1a and 1b, there are projectingly provided a plurality of opposite pairs of vertical guide ribs 1c at certain pitches in the longitudinal direction.
- the pitch of two adjacent ribs 1c is slightly larger than the thickness of one single tape cassette so that only one cassette can be detachably accommodated in the space between the two adjacent ribs 1c.
- the lower ends of each opposite pair of the guide ribs 1c are connected with each other by a beam 1d, and a longitudinal beam 1e extends through the centers of the beams 1d.
- Upper ribs 1f, 1g, 1h and 1i and lower ribs 1j, 1k, 1l and 1m horizontally extend outwardly from the upper and lower peripheries of the magazine container 1 respectively.
- the upper and lower ribs 1f and 1j as shown in the left-hand direction project outwardly with a larger lateral size than that of each of the upper and lower ribs 1g and 1k in the right-hand direction, and the upper rib 1f in the left-hand direction is longer in vertical length than the other ribs so that the magazine container 1 is transversely assymmetrical in its outward configuration.
- the outer face S1 of the front wall 1n of the magazine container 1 is formed with a rough face i.e., an aventurine face, while the outer face S2 of the rear face 1o of the container is formed with a smooth face so that an operator can recognize the front face and the rear face by hand.
- the tape cassette to be treated by the apparatus of the present invention is substantially formed by a top case 2a and a bottom case 2b made of plastic and assembled together by tapped screws 3, and contains a pair of tape hubs 4 to which both ends of a leader tape are connected with the intermediate portion of the tape being passed through a tape path.
- the untreated cassettes 2 are inserted into every space between each pair of the guide ribs 1c adjacently provided in the longitudinal direction of the magazine container 1 with the tape travelling surface directed upward. In the embodiment as shown in FIG. 1, about 30 cassettes 2 may be contained in one magazine container 1.
- FIG. 2 is a schematic view of the entire body of a cassette treating apparatus used in the present invention, which includes a first cassette supplying apparatus 5 in its upper portion in which the magazine container 1 containing a plurality of tape cassettes 2 is first inserted and then vertically reversed so that each of the tape cassettes 2 is successively fed to the next stage with the tape travelling surfaces of the cassettes 2 directed downward.
- the tape cassettes 2 are then fed to a second tape cassette supplying apparatus 6 provided below the first cassette supplying apparatus 5 to be successively forwarded in series along a linear dropping passage of a certain length into a predetermined treating portion.
- a tape cassette treating apparatus for treating the appropriately positioned tape cassette 2 by rotating the hubs thereof to examine the efficiency of the magnetic tapes, record information such as music or set magnetic tapes to cassettes provided only with leader tapes.
- the treating apparatus is used to load magnetic tape.
- the magnetic tape loading apparatus draws out the leader tape RT in the form of a loop from openings in the tape path surface of the cassette 2, severs the center of the loop and successively joins the severed ends of the leader tape RT together with both ends of a magnetic tape MT of a certain length drawn out from a magnetic tape winder 7 to wind the joined tape around one of the tape hubs 4.
- the apparatus according to the present invention further includes under the treating apparatus a tape cassette discharging apparatus 9 for receiving the treated casseete 2, turning the same by about 90° in the front side of the body of the apparatus and transferring the same downwardly.
- a treated cassette collector 10 which functions to support a number of tape cassettes 2 turned and fed to a certain position transversly in a line and move the cassettes 2 in a lump into a hollow magazine container 1 transversely set thereunder beforehand.

- the disc-shaped wheels 15 and 16 are supported through guide rollers 17 fixed to the frames 11 and 12 to rotate around the longitudinal axis as indicated by a symbol x.
- the front frame 11 and the front disc-shaped wheel 15 have openings 18 and 19 respectively for longitudinally treating the magazine container 1 therethrough, and the stays 13 and 14 have guide grooves 20 and 21 (FIG.
- the guide grooves 20 and 21 have different depths d1 and d2 so that the magazine container 1 is not reversely placed in the longitudinal direction.
- the magazine container 1 is forcibly pushed in the first cassette supplying apparatus 5 in the longitudinally reversed condition, and therefore the outer surfaces S1 and S2 of longitudinal side walls 1n and 1o are made course and smooth respectively so that the direction of the magazine container 1 may be found by hand when pushing the same into the first supplying apparatus 5, thereby doubly preventing any error in setting the magazine container 1.
- the wheels 15 and 16 hold the magazine container 1 therebetween and vertically rotate to downwardly discharge the cassettes 2 in the magazine container 1 all together. This operation is conducted by a magazine container reversing mechanism 22.
- the reversing mechanism 22 comprises a gear 23 in the form of a large-diametrical ring secured to the rear surface of the rear wheel 16, and a pinion 24 which engages with the gear 23 and an electric motor 25 for normally and reversely driving the pinion 24 provided in the rear frame 12.
- a pin 26 (FIGS. 3 and 7) for limiting the angle of rotation of the gear 23 and the rear frame 12 has an arcuate slit 27 defined corresponding to the rotation phase angle of 180° for receiving the pin 26.
- the pin 26 is to contact with respective stoppers 28 provided on both ends of the slit 27 to limit rotation of the wheel, and the limits of rotation are detected by limit switches 29 operated by the pin 26.
- Stoppage of reverse driving of the motor 25 is thus controlled by operation of the limit switches 29.
- a pair of magazine container supporting rods 30 opposite to the upper ends of the transverse side walls 1a and 1b of the magazine container 1 to receive and support the vertically reversed magazine container 1 with the wheels 15 and 16.

- the rear frame 12 further has a pusher 33 and an air cylinder 34 for longitudinally driving the pusher 33 so that the pusher 33 moves in and out from an opening (not shown) in the rear wheel 16 through the interior of the ring-shaped gear 23.
- the pusher 33 shifts the same forwardly to a predetermined position so that all of the cassettes 2 in the magazine container 1 are displaced from the ribs 31 and are simultaneously dropped downwardly.
- a successive cassette dropping mechanism 35 for recieving and supporting the cassettes discharged from the magazine container 1 in a line, progressively forwarding the cassettes 2 and successively feeding the same downwardly.
- the cassette dropping mechnism 35 is shown in detail in FIGS. 5 and 6, and comprises a base frame 36 provided perpendicularly against the longitudinal frames 11 and 12, a transverse pair of horizontal supporting rods 37 secured to the upper portion of the base frame 36 for receiving and supporting the reversed and dropped tape cassettes 2 and a pair of vertically wide feeding rods 39 provided upwardly of the horizontal supporting rods 37 for guiding the dropped tape cassettes 2 in a line at regular intervals by a plurality of pairs of ribs 38.
- the feeding rods 39 are secured to a pair of rotatable and axially reciprocatable horizontal supporting shafts 40.
- a pair of cassette connecting rods 42 having a plurality of ribs 41 which are identical in pitches with the ribs 38.
- the connecting rods 42 are fixed to movable blocks 44 which are slidable along fixed slide guiding shafts 43 transversely placed on the base frame 36 and are drawn by pressure toward the center by a spring 45.
- the movable blocks 44 are connected through links 47 with rotatable arms 46 connected in a spline-like manner with the central portions of the supporting shafts 40, and upon rotation of the supporting shafts 40, the feeding rods 39 transversely move and simultaneously the connecting rods 42 linearly move in the opposite direction.
- the feeding rods 39 and the connecting rods 42 are in conditions as indicated by full lines in FIG. 6 and the cassettes 2 are guided by the ribs 38 of the feeding rods 42 to be supported by the supporting rods 37 in line in the longitudinal direction. Subsequently, when the respective supporting shafts 40 are retracted backward in a predetermined length, the ribs 41 support the respective tape cassettes 2 to stand vertically preventing them from falling down. Then the feeding rods 39 are retracted with their opened state as shown in FIG. 6.
- the feeding rods 39 are rotated inwardly to stand vertically while the connecting rods 42 are displaced outwardly to the original position for supporting the respective tape cassettes 2 by the ribs 38 of the feeding rods 39.

- the other end of the link 62 to rotatably engaged with the eccentric cam 61 which is supported on the cam shaft 55 so that upon rotation of the cam 61, the link 62 is swung in the vertical plane with a predetermined angle, thereby causing the movable block 58 to be reciprocated vertically resulting in swinging both of the arms 56 to rotate reciprocally the supporting shafts 40 with a predetermined angle.
- each of uppermost or first guide members 48 has a length for accommodating one tape cassette 2 with the short side of the cassette directed vertically.
- a pair of lower or second guide members 70 for retaining a plurality of tape cassettes 2 with the vertical attitude and lined up one above the other. In the embodiment shown in FIG. 8, three tape cassettes can be retained in the lower guide members 70.
- a limit switch 71 is provided on the upper guide members 48 for detecting the presence of the tape cassette 2 between the upper guide members 48.
- a pair of braking rollers 72 which are adapted to contact resiliently to the surface of the tape cassette moved downwardly along the second guide members 70 so that the rollers 72 give a braking force on the tape cassette to slow the dropping speed of the tape cassette 2.
- a reception take up frame 73 is located just below the lower guide members 72.
- a pusher 75 is provided opposing the take up frame 73 for displacing the tape cassette 2 by means of a pusher member 75' which is moved by an air cylinder 74 in a direction as shown by the arrow marks x'-X" in FIG. 8. It is noted that X as a" is defined as a frontward direction and X' backward direction.
- the bottom of the second guide members 70 is opened to allow the tape cassette 2 to drop out of the second guide members 70, on the other hand, when the pusher member 75' is in the projected position, the bottom of the lower guide members 70 is closed by the top surface of the pusher member 75' to support the tape cassette 2 which remains in the guide members 70, while the tape cassette 2, which already dropped from the guide members 70, is displaced frontwardly and being thrown into a vertical path 76a defined by the pair of third guide members 76 to transfer the tape cassette 2 in a downward direction to the subsequent stage exhibiting a vertical attitude of the tape cassette.
- a limit switch 77 detects presence or absence of the tape cassette 2 in the take up frame 73.
- a slider 133 serves to take a leader tape RT out of the tape cassette 2 by attracting the leader tape RT onto the top face of the slider 133 by vacume in turn the slider 133 is moved leftward to retract the leader tape RT from the tape cassette, so that the end of the leader tape RT is brought to a bonding block 131, where the leader tape RT is cut by the cutter 134 then the end of the leader tape RT is bonded with an end of the magnetic recording tape MT released from the original roll 7 of the magnetic recording tape by means of a splicing tape ST. Subsequently the magnetic recording tape is taken up by the right side hub of the tape cassette 2 which is driven by a drive shaft 135 mounted on the apparatus 6.
- the corresponding end of the magnetic recording tape RT is cut by the cutter 134 with its end bonded with the end of the leader tape RT attached to the left side hub in the tape cassette 2 by means of a splicing tape ST.

- the respective links 103a and 103b are secured and the free ends of both of the links 103a and 103b are movably linked together by a pin 103d passed through the respective elongated holes 103c.
- the pin 103a is also rotatably linked with the top end of the piston 104a of the air cylinder 104 so that both of the links 103a and 103b are rotated in the opposite direction relative to the both of the supporting shafts 94a and 94b.
- the supporting rods 95a and 95b are swung in opposite directions so that the supporting rods 95a and 95b come to the area below the both of the cassette feeding rods 97 or leave the area to allow to drop the respective tape cassettes supporting on the supporting rods 95a and 95b.
- the cassette feeding rods 97 are provided with the gears 105 at the rear end portion thereof and the engaging rods 99 are also provided with the gears 106.
- the gears 105 and 106 are engaged together so that upon rotation of the gear 105 the feeding rod 97 and the engaging rod 99 are rotated in a opposite direction.
- Both of the gears 105 are engaged with the corresponding gears 109, which are driven by the reversible electric motor 107 through the drive gear 108 to rotate the left hand gear 109a and the right hand gear 109b in an opposite direction as shown in the arrow marks in FIG. 17, thereby causing the cassette feeding rods 97a and 97b to be rotated in the opposite directions.
- the both ends of the cassette feeding rods 97a and 97b are connected by the stay 110, the intermediate portion of the stay is linked to the drive member 112 through the link member 113.
- the drive member 112 is driven swigingly to and fro by the reversible electric motor 111, so that by swing motion of the electric motor 111 both of the cassette feeding rods 97a and 97b are simultaneously reciprocated with a same stroke length as the pitch between the two adjacent ribs 98 of the feeding rods 97.
- the length of the both of the gears 105 is so designated that each of the gears 105 and the corresponding gear 105 are always engaged together in spite of the displacement of the cassette feeding rod 97.
- a pair of adjusting screws 114 are adjustably secured to a fixed member 200 with the free end of each of the screws 114 opposed to the stay 110.
- the length of the stroke of the cassette feeding rods can be limited by abutting the stay 110 onto the rear end of the screw 114.
- a limit switch 115 is disposed to detect the angular value of swing motion of the drive member 112 so that when the limit switch 115 is activated by the end of the drive member 112, the motor 111 is stopped to limit the swing angle in the backward direction.
